Pros:
- The battery. It uses AAA batteries..so even if i get caught with empty batteries, I could replace it easily, instead of waiting 4 hours just to recharge Reader's battery. More page "flips" too. (my main reason to get Librie instead of Reader)
-Patchable to english
-it has a mini keyboard, so im guessing the dictionary should be easier to use, though slow (english is not my native language, i'd need some handy help)
-i might be able to get it from singapore (i'm in indonesia)

Cons:
BBeB
But i dont really mind it. Most of the stuff i want to read, i have the "masters" in html, txt and pdfs. Spending some minutes to convert it shouldnt be much trouble. I'll consider it as time taken to drive to a bookstore to get paper books. and because i'd still have the masters, i can change to next generation ebook reader later without worrying too much.

For page refresh time, I saw the video, and decided that its not that bad.

well...Sony is not being very clear about file formats support.
I just visited Librie yahoo group and found this on a message about Sony taking pre-orders on Readers:
"More than eBooks
The Sony Reader isn’t just about reading eBooks. Using the included CONNECT™ Reader PC Software, you can easily transfer Adobe® PDF documents, BBeB Book, and other text file formats to the Reader. Seamlessly search, browse and download user-selected RSS Web content from CONNECT™ Store to the PC and transfer to your Sony® Reader. Take along your favorite Web newsfeeds, blogs and more to read where ever you are."

The Reader is, of course, the latest device, hence some new features, including native PDF support. (Meaning you can load PDFs directly.) One caveat: according to an Adobe blog, the Sony Reader's PDF viewer cannot reflow text.
